Isochoric Differential Apparatus

Application domain(s)

  • Advanced Materials
  • GreenTech

Area(s) of expertise

  • Renewable Energies


IDA, Isochoric Differential Apparatus is a volumetric instrument for the characterization of material about gas sorption, especially in hydrogen storage study. Differential approach consists in the simultaneous comparison of pressure measures during a sorption phenomenon with a blanch test, which allows to achieve higher accuracy on gas uptake/release and reduce nonlinear or temperature effect  caused by gas expansion

Advantages & Applications

  • High accuracy: less than 10-5 moles
  • No wait time in the first step of sorption phenomenon, where quick pressure changing can affect the measurement
  • Measuring ranges limited only by type of sensors: vacuum to  30 Bar, RT to 650 K
  • Possibility to perform surface study, as BET
